Run the 3.0.x CI on Drupal core 11.4.9, which has the Twig 3.30 fix

Problem/Motivation

Re-running the 3.0.x pipeline now builds Drupal core 11.4.6 with twig/twig 3.30.0. That pair renders every page as a fatal TypeError, fixed in core 11.4.8 by #3625969. The functional testing job fails all scenarios with a 500 (job 12785979), which blocks the 3.0.1 release in #3629874.

Proposed resolution

Run the 3.0.x CI on core 11.4.9, which has the Twig fix, the same change 3.1.x gets in #3629811. CI only, no module code changes.

MR !76 is green in pipeline 997078 (core 11.4.9, Twig 3.30.0).
